Powered tools have brought great benefits to building trade, as well as extending the scope of possible projects for DIY enthusiasts. However, whilst tools such as the electric drill tend to spring to mind as the classic powered tool, electricity is not always required. Indeed, air tools can offer considerable benefits over tools requiring a mains socket.
The primary benefit of air tools is that they tend to pack more of a punch than traditional powered tools. They can be more powerful, because they offer relatively more torque. Torque is essentially the amount of force deployed to turn object round its axis. Garage mechanics, for example, value the torque provided by pneumatic impact wrenches, which are used to unscrew reluctant bolts from tyre fittings. The home hobbyist will also welcome the power provided by a nail gun, which provides a rapid screwing motion; very helpful when putting up shelves. Home hobbyists are also drawn to the lightweight, portable, pneumatic drill, as an alternative to electric drills.
Meanwhile, air tools have a reputation for durability. Their tough metal casings derive from usage on industrial worksites. Moreover, air tools tend not to have as many moving parts as their electric counterparts, and therefore fewer components can become worn with repeated use.
Finally, air tools, lacking electric motors, tend to be less expensive than their electric counterparts. Air tools rely on a separately purchased air compressor, which can be used for multiple devices. Hence the tools themselves tend to be cost effective over the years.
